I V/ALmEx/S allied streams of water are thrown from Patented Oct. 8,1929 UNITED STATES PATENT OFFICE HERMAN E. KEINE, OF MILWAUKEE,WISCONSIN, ASSIGNOR TO BRADLEY WASHFOUN- TAIN GOMPANY, OF MILWAUKEE,WISCONSINfA'CORPORATION 0F WISCONSIN WASILFOUNTAIN SPRAY HEADApplication led September 27, 1926. i Serial No. 138,078.

This invention relates to improvements in washfountain spray heads.

Heretofore, heads for washfonntains have been so constructed that aplurality of closelly "ne head.

The present invention, however, has for its object the provision of aspray head which will discharge a sheet or curtain of water instead ofthe individual streams, as heretofore.

A further obyect of the invention is to provide a washfountain sprayhead which is of simple construction, is strong and durable,

is efficient in ope ation, and is well adapted for the purposedescribed.

lVith the above and other objects in view, the invention consists of theimproved washfountain spray head and its parts and combinations as setforth in the cla-im and all equivalents thereof.

In the accompanying drawing in which the same reference charactersindicate the same parts in all ofthe views:

Fig. l is a side view partly in vertical section of the iinproved sprayhead;

F ig. 2 is an enlarged f ii'agmentary detail view thereof, partly insection; and

Fig. 3 is a fragmentary diagrammatic plan view showing the nature of thesheet of water discharged from the spray head.

Referring now more particularly to the drawings, it will appear that thenumeral 8 indicates a spray head casing which is preferably of curvedform in horizontal plane. The casing is provided with an inlet opening9, communicating with an interior chamber 10 into which water isadmitted by means of a Valve 1l to be discharged by the spray head.

The outer periphery of the spray head is provided with a curved line ofradial ontwardly and downwardly directed spray .apertures 12 throughwhich water is discharged for washing purposes. The exterior of the headis provided with a groove 13 connecting all of said spray apertures.

l-Ieretofore, in spray heads constructed with the spray aperturesunconnected, the result has been a discharge of a plurality of minutestreams. However, the present device, by means of the slot connectionbetween all of the spray apertures, discharges a sheet or curtain ofwater. So far as can be deter mined, the physical cause of this actionis that the proximity of the apertures in the spray 'head and thehorizontal connecting groove causes the water when leaving the aperturesto spread. The spreading of the water, in combination with the surfacepressure peculiar to water when released, causes the wat-ei.' to combinein a solid circumferential sheet. The advantages of the discharge of asheet of water or curtain,over a solid stream as discharged from afaucet is the economy of water consumption, and the convenience to theuser. n

From the foregoing description, it will be seen that the improved sprayhead is of very simple and novel construction, and is well adapted forthe purposes described.

What I claim as my invention is:

A. spray head, consisting of a casing of carved form in horizontal planeand formed with a curved line of outwardly and downwardlydirected sprayapertures, said casing also having an exterior elongated grooveintersecting all of said apertures, said groove being of less width thanthe diameter of a spray aperture and materially of less depth than theaxial extent of said aperture wherelOO
